  • the instant motor mounting means is herein disclosed in conjunction with an electric motor of the gear-drive -typethat is, permitting the abovementioned tooth-mesh adjustment between same and an associated driven gear, it is axiomatic that such invention may be equally well adapted for use with motors of the pulley-drive type, where belt tensioning may be quickly and easily adjusted between the sheave of the driving motor and the associated sheave causedto be driven thereby.
  • the primary object of the instant invention is actually twofoldof providing novel mounting means adapted to electrically insulate the drive motor from the particular machine to which it is applied and, while so doing, he likewise adaptable for accurately adjusting the motor carried driving member with respect to that power trans- -mitting member first caused to be driven thereby.
  • the instant mounting means is, in addition to the motor per se, made up of but four different elements, each of which is especially designed to interconnect and be associated with the other, all without the use .of bolts, screws, or any other means more or less permanently aflixing same to the machine proper.
  • the invention includes certain novel features of construction and combinations of parts, a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.
  • FIG. 1 is a schematic representation in partial section of the various elements going to make up the instant invention
  • FIG. 2 is a front perspective view of a representative type of machine which might normally embody the instant invention, being specifically a cash register in this instance;
  • FIG. 3 is a sectional view in side elevation showing those elements of FIG. 1 in their motor fixing and insulating position;
  • Patented June 14, 1966 to include the present invention is housed in a suitable cabinet 10 and has, although not illustrated herein, the
  • the side frame 15, at such zone of motor mounting is provided with what may be defined as a splined or keyed aperture 16 therethrough-that is, being a round hole with a plurality of spaced-apart notches or slots 16a around and within its periphery. While any convenient number of such slots 16a may be provided, the present disclosure makes to be rotated within the aperture 16, the central bore 17b thereof continually changes its position with respect to the center line of such aperture 16. Integral with the member 17 is a fixing lug 17c which, as understood from FIG. 5, may be received within any one of the plurality of notches 16a provided around the side frame aperture 16.
  • the insulating and adjusting member 17 is positively fixed against rotation within such aperture 16 and,'as determined by the slot or notch 16a selected for receiving the fixing lug 17c, the inner bore 17b of such member 17 is precisely located at a selected position within the aperture 16.
  • Such selected position may be quickly and easily changed by removing the fixing lug 17c from one notch 16a and presenting same within any one of such other like notches 16a.
  • a major-diameter portion 17d .of the insulating and adjusting member 17 abuts against the side frame 15-that is, comes to rest against that area of the side frame adjacent the aperture 16 therethrough (see also FIG. 3).
  • a plurality of integral notches 17e surround the internal surface of the major-diameter portion 17d of such member 17, each of which is of that width to slidingly receive a motor carried fixing lug 19 therewithin (see FIGS. 1 and 4).
  • the fixing lug 19 itself is an integral part of a motor mounting nose 18' of that diameter to slidingly enter within the insulating and adjusting member inner bore 17b; hence permitting the motor 13 to both be fixed rotatably within the insulting and adjusting member 17 and be spaced a distance from the machine framework side frame 15, as the lug 19 enters within the receiving notch 17s and the front surface of the motor 13 itself is moved against the rear surface of the insulating and adjusting member major-diameter portion 17d (FIG. 3).
  • nipple 21 Surrounding such drive shaft 14 is a screw-threaded nipple 21, which nipple 21 is fixedly positioned between the motor mounting nose 18 and the motor driving member 20, and which nipple 21, along with such driving member 20, are of that diameter to fit freely within and through the inner bore 17b of the insulating and adjusting member 17 (FIG.. 3).
  • both the driving member 20 and the nipple 21 are each of a lesser diameter than that of the inner bore 17b, the driving member 20 is likewise of a lesser diameter than such nipple 21 in order that a locking nut 22 may be freely received thereover and screw-threadedly engaged with such nipple 21.
  • the nipple engaging end of the locking nut 22 is provided with a peripheral flange 22a which engages behind the forward nose portion of each of a pair of diametrically opposed retaining fingers 17f provided integral with the insulating and adjusting member minor-diameter portion 1711 (see also FIGS. 3 and 5).
  • the diameter of such locking nut peripheral flange 22a is approximately that of the insulating and adjusting member inner bore 17 b; 'hence permitting such peripheral flange to be slidingly received within such inner bore, whereas the retaining fingers 17 have their forward nose portions of that thickness to extend normally within the diameter of such inner bore.
  • the peripheral flange 22a thereof first springs each of such retaining fingers 17 f slightly outwardly and thence becomes retained behind the finger nose portions as the nut 22 is moved inwardly to that extent permitting the fingers 17 f to return to normal.
  • the locking nut 22 is effectively coupled with the insulating and adjusting member 17 and can remain so even though the motor 13 is, for maintenance and the like, caused to be removed from the machine proper.
  • this flange and finger arrangement permits the locking nut 22 to be snapped within the insulating and adjusting member 17 prior to receipt of the motor mounting nose 18 within the inner bore 17b there- .of, all being (101.
  • each side surface of the peripheral flange 22a is appropriately bevelled so as to effect the outward springing of the retaining fingers 17 in each instance that is, both when the locking nut 22 is moved inwardly to a coupling position with respect to the insulating and adjusting member 17 and when same is moved outwardly to an uncoupling position with respect thereto.
  • an excellent means is provided for supporting the motor 13 solely by one side frame 15 of the machine using same. Furthermore, the motor 13 so supported can be selectively shifted with respect to the axial center line of the aperture 16 through the side frame 15, being thus precisely adjusted with respect to the machine carried driven member first caused to receive movement therefrom.
  • the driving member 20 on the motor shaft 14 is in the form of a gear or pinion intermeshing with a companion gear 24 supported rotatably on a stud 25 fixed in the side frame 15 (FIG. 3). In this instance, precise tolerances between the meshing of the teeth of the several members 20 and 24 can be initially had during motor assembly and continually maintained throughout machine use, all in the following quick and simple manner.
  • both the insulating and adjusting member 17 and the ring washer 23 are designated as being made of a plastic or like dielectric material. This, as is clear from FIG. 3, insulates both the motor 13 and the locking nut 22 from the machine framework side frame 15 and, if the companion gear 24 is likewise made of a material of similar type (being usually fiber for noise reduction purposes), a complete electrical insulation between the machine proper and its driving motor 13 is had.
  • the instant invention may be used just as well for machines of the pulley-drive type to maintain adequate belt tensioning between the driving member 20 and a companion sheave. This is likewise true with respect to sprocket-drive type machines for maintaining proper chain tension with respect to a driving member 20 of the sprocket configuration.
  • said flanged member fixing means comprises a plurality of key slots around said frame plate aperture, and a corresponding lug memher on said one diameter portion for selective engagement therewith.
  • the mounting means of claim 5 including coupling means between said insulating and adjusting member and said locking nut, whereby the one diameter portion of said insulating and adjusting member may be inserted through the frame plate aperture and said locking nut interconnected therewith prior to assembly of the machine motor.
  • the nipple engaging end of said locking nut is provided with a peripheral flange therearound; said further member comprises a ring washer engaging freely over the one diameter portion of said insulating and adjusting member; and flange engaging fingers are provided on the one diameter portion of said insulating and adjusting member for maintaining the assemblage of said insulating and adjusting member, said ring washer, and said locking nut coupled to the motor supporting frame plate.
  • said flange engaging means comprises a pair of resilient retaining fingers each having a forward nose portion normally aligned in the path of travel of said locking nut peripheral flange; and said locking nut peripheral flange is appropriately bevelled so that, when forced against the forward nose portions, said retaining fingers will be yielded thereby and permit the flange to move therepast before returning to normal.
